Fire rated sealant in Puddle Dock

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Do not paint over fire sealant until it has cured
  • Look in service cupboards and ceiling voids from time to time
  • Flag any open gap you spot round a pipe or cable
  • Ask every contractor to reseal any fire stopping they disturb

Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

About our fire rated sealant in Puddle Dock

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. Common call-outs are for gaps around pipes and cables through fire-resisting walls and fire seals that have cracked with movement, on pipe & cable gaps, linear gaps and flats & HMOs.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Puddle Dock cannot close.

You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

Do you need fire rated sealant in Puddle Dock?

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Keep an eye out for these signs:

  • Fire stopping disturbed by later work
  • Gaps flagged on a fire risk assessment
  • Linear gaps at the head of walls
  • New service routes left unsealed after building work

Schools such as The James Oglethorpe Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Choosing a sealant specialist

Different surfaces, different methods

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before any work starts.

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

What fire rated sealant looks like in Puddle Dock

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.

Puddle Dock is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a church, hall or community building such as Moor Lane Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Puddle Dock is about 3 miles north of South Ockendon, in Greater London.

What we do, step by step

Before we leave, we go over the finished joints with you. The work normally takes a few hours for a handful of gaps, and longer for a whole building, depending on how much there is to do. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Puddle Dock. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

How to prepare

  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in
  • Mention any parking rules near the property

Puddle Dock: your questions answered

Is Puddle Dock in your area for fire rated sealant?

Yes, Puddle Dock is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.

Can parking be tricky for a visit in Puddle Dock?

Parking in Puddle Dock, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Do you certify the fire stopping?

We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and giving you a record of where it went.

Do you hold any approvals?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can you match the sealant colour?

In most cases you can choose. We will explain which colours are available and agree one before any work starts.

Can tenants book the work?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.

How long does fire rated sealant take?

Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.

When it is not the sealant

In fairness, some problems need a different trade:

  • Construction that does not provide fire resistance on its own
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone isn’t the tested solution

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What we seal

  • Flats & HMOs
  • Pipe & cable gaps
  • Linear gaps
  • Door frames
  • Service penetrations
  • Plasterboard & masonry

What happens if it’s left?

Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Puddle Dock, the repair is bigger than the sealant job would have been.

The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
